1. Zero-Server-Storage & Client-Side Sandboxing
Unlike traditional web applications that transmit user inputs to remote databases or cloud servers for compilation and rendering, Online HTML CSS Editor executes 100% within your client browser.
When you type HTML, CSS, or JavaScript into the editor, the code is evaluated and rendered locally via an isolated iframe running on your device's V8 / JavaScriptCore engine. At no point is your editor content transmitted to, inspected by, or stored upon our web servers.
We cannot read your code. Even if a government, third-party entity, or automated crawler demanded access to the projects or code you write on our platform, we have zero technical ability to provide it, because it does not exist on our servers.
2. Data We Do Not Collect
To ensure total user peace of mind, we explicitly declare that we do NOT collect, harvest, or monetize:
- Your Code Content: No markup, stylesheet rules, JavaScript functions, or text files are saved to any cloud database.
- Personal Identities: We do not require accounts, usernames, passwords, credit card numbers, or email signups to use any standard editing features.
- Keylogging or Behavioral Recording: We do not record your keystrokes, typing speed, or code modifications.
- Export Archives: Projects exported via our ZIP tool are bundled entirely in-memory using client-side JavaScript (JSZip) and downloaded directly to your local file system.
3. Local Storage (Browser Persistence)
To maintain your workflow between visits, the editor utilizes the browser's standard localStorage API. This data resides strictly on your physical machine and is never transmitted over the network:
| Storage Key | Purpose & Stored Information | Retention |
|---|---|---|
ohe_playground_store_v1 | Saves your active code draft, selected editor layout, split panel proportions, and theme preference. | Persistent on device until browser cache is cleared. |
ohe_ui_lang | Stores your chosen UI language (e.g. English, Spanish, German, Japanese). | Persistent on device until browser cache is cleared. |
You can instantly reset or erase this data at any time by clicking the "Reset Boilerplate" button in the editor toolbar, or by clearing cookies/site data in your browser settings.
4. Optional AI Coding Assistant (Opt-in)
The editor features an optional AI coding assistant to help troubleshoot bugs and explain code snippets. Use of this feature is strictly voluntary and user-initiated.
When you explicitly press the AI assistant prompt button, only the code snippet and your specific question are sent via encrypted HTTPS/TLS to the AI processing model. These interactions are processed on-demand and are not used to train global public foundational models or sold to third parties.
6. External CDNs & Script Injections
If you choose to link external stylesheets or scripts inside your preview (such as Google Fonts, Font Awesome, or Bootstrap via CDN), your browser connects directly to those third-party providers. Those external requests are governed by the respective providers' individual privacy policies.
8. Your Rights (GDPR, CCPA & Global Frameworks)
Under global privacy regulations including the EU General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA):
- Right to Access & Portability: You can export all your project data at any time using the one-click ZIP Export tool.
- Right to Erasure (Right to be Forgotten): Because we store no personal data or code on our servers, clearing your browser's local cache immediately and permanently erases all session traces from your device.
- Right to Non-Discrimination: Online HTML CSS Editor is completely free and accessible without any requirement to waive privacy rights.
